Pay attention to snow accumulation in your area as amounts vary significantly across the bulletin region.Moderate rating at tree line meant for areas of higher precipitation total.
Sensitivity and consequence of this new slab may be increasing with incremental loading. These slabs are sitting on previous hard surfaces (old wind slabs, temperature and sun crusts).
Persistent slabs present above 1950m as a buried facet layer down 20-40cm is the primary concern, however there has been a lack of natural avalanche activity on this layer in the recent days.
Sunday:Mainly cloudy with scattered flurries.Accumulation: 4 cm.Alpine temperature: High -12 °C.Ridge wind east: 10 km/h.
Freezing level at valley bottom.
Monday:A mix of sun and cloud.Precipitation: Nil.Alpine temperature: Low -31 °C, High -26 °C.Ridge wind east: 15 km/h.Freezing level at valley bottom.
New wind slabs in the alpine and exposed tree line from strong SW winds and incremental precipitation. Weak temperature crust up to 1900m and solar crust on solar aspects up to 2800m. December facets down 20-70cm, showing signs of rounding within bulleting region. Basal facets & depth hoar present throughout area up to 30 cm off the ground.
Icefields patrol and Maligne field team did not observe any new natural avalanche activity. Visibility was fair overall.
